`SHOCK-LOADER.

SPECIFICATION forming part 0f Letters Patent No. 716,250, dated December 16, 1902.

y Application led MayZG, 19.()2I Serial No. 108,912. (No model.)

To all whom/rt may concern,.-

Be it knowuthatLHELMnn O. KoLsBUN, a citizen of the United States, residing at Etter, in the county of Dakota and State 0f Minnesota, have invented certain new and useful Improvements in Shock-Loaders, of which the following is aspeci'fication.

My invention relates to improvements in shock-loaders, its object being to Aprovide means in connection with a wagon or rack adapted to be actuated in the travel of the vehicle to lift shocks from the ground and deposit themlupon the wagon. p v

To this end myinvention consists in the features of construction and combination hereinafter particularly described and claimed.4

In the accompanying drawings, forming part of this specification, Figure l represents.

a rear elevation of a wagon embodying my improvements. Fig. 2 is a partial side elevation Fig. 3is'a section through the wagon-box on line a: `of Fig. 2showing the shock-lifting mechanism extending beyondthe sideof the wagon with the shock-engagin g means inraised position. Fig. 4 is a top View of the `upper horizontal beam of the lifting mechanism. Fig. is a top view of the shockactuated tripping-lever forming partof myinvention. Fig. 6 is a detail of a lever forming part of the actuating mechanism. Fig. 7 is a detail of the shock-engaging arms. Fig. 8 is a detail of a cross-barcarried by the supporting-rods of the shock-lifter. Fig. 9 is a section through the lower end of the main standard, showing the connected framework partially brokenaway. Fig. 10 is a side elevation of one feature of the tripping mechanism. Fig. l1 is a plan View of the same; and Fig. 12 is a plan View of the machine in the position shown in Fig. 1, partially broken away.

In the drawings, A represents a wagon mounted on suitable Wheels 2. Carried by the rear of the wagon is the vertical standard 3. Having swinging support upon the upper end of the standard 3 is a horizontal arm or beam 4, carrying collars 5 and 6, surrounding the standard. Vertically slidable in the outer end of the beam 4 are rods 7, carrying at their lower ends,v the shock-lifter B. The shock-lifter B consists of a pair of arms 8, having pivotal connection 9 and being supported from the ends of the rods 7 by links 1Q.

The upper ends of the arms 8 are connected by levers 11 with an eye 12, to which is connected the cable 13. The cable 13 runs over a pulley 14 in the end of the beam 4, thence passing around a roller 15 and around the reel 16, mounted upon the horizontal shaft 17. Secured alongside of the reel 16 is a sprocketgear 18,0onnected by a sprocket-chain 19 with a sprocket-gear 20, loosely' mounted upon the shaft 21. Mounted upon the outer end of the shaft 2l is a sprocket-gear22, connected by a chain 23 with a gear 24,secured upon the hub 25 of the rear wagon-wheel, as shown in Fig. 2. Carried by the sprocket-gear 20 is a cluch member 26,adapted to interlock with a slidable clutch member 27, feathered upon the shaft 21. In order to actuate the clutch member 27, I provide a yoke 28, inclosing such clutch member and connected with a lever 29, having fulcru x11-support 30 upon the framework. The Lipper end of the lever 29 is connected by a chain 3l with one side of the collar 5, and the lower end of the lever 29 projects alongside the rear edge of the Wagon and is connected by a spring 32 with the framework. In order normally to hold the clutch members in released position, as shown in Fig.. 1, I provide a notched plate 33, in engagement with which the lower end of the lever 29 is held by means of a spring 34, secured to the outerside of said lever and engaging at its freeend with the strap 35. i l

In order to actuate the lever 29 to throw the clutch members into engagement, I provide the following parts: Loosely mounted upon the bolt 36, passing through the rear cross-bar of the wagon, is the bar 37, carrying upon its upper end an outwardly-projecting cam 38, adapted to engage with the lower end of the lever 29. The lower end of the bar 37 is normally held forced outward by means of the spring 39. Projecting rearwardly from the wagon is a bar. 40, uponthe end of which is pivotally supported the lever 41, one end of the lever standing outside the lower end of the bar 37 and the opposite end of the lever having hinge connection 42 with an arm. 43, the arm 43 being normally held in alinement with the lever 41 by a spring 44. In order to hold the supporting-arm 4 in the position shown in Fig. l, I provide the collarband 45, having pivotal support 46 in the Ioo framework. One end of the collar-band is rectangular and surrounds the sta-ndard 3, and the opposite end is pivotally connected with a lever 47, having pivotal support 48, the free end of the lever 47 being provided with an opening through which passes one of the rods 7. Aspring 49 is interposed between the inner end of the collar-strap and the framework above to hold the end of the collar-strap belowr the roundl portion 50 of the standard 3. The inner end of the collar-strap thus normally tits the rectangular portion of the standard 3, preventing turning of the collar-strap, and consequently holding the beam4 in outturned position. As the shocklifter is raised in the operation of the machine the cross-bar 5l comes in contact with the free end of the lever 47, turning said lever upon its pivotal support 48 and turning the collar-strap against its spring 49 to carry the inner end of the strap to the round portion 50 of the upright standard 3, allowing the arm 4 to be swung inward overlthe wagon. A stop 52 is provided to limit the outward swinging of the arm.

In Fig. 1 the parts are shown in position ready for use. As the wagon is drawn over the ground the clutch member 27 will be continuously revolved by means of its connection with the wheels 2. As the arm 43 strikes the shock the connected lever 4l will be turned upon its pivot, actuating the bar 37 and the lever 29 to throw the clutch member 27 into engagement with the clutch member 26.` This will throw the reel 16 into operative connection with the wheels through the medium of the sprocket-chain 19 and clutch member 26, causing the reel to be actuated to wind up the cord 13. The result of this is to rst close the arms of the shock-lifter upon the shock, as illustrated in Fig. 3, thereafter raising the shock-lifter. As the shock-lifter is raised the cross-bar 5l will be brought in contact with the end of the lever 47, turning the collar-strap to the circular part of the upright standard 3, as hereinbefore described. The continued winding of the cord 13 will swing the main supporting-arm 4 inward over the wagon. As the arm 4 is swung over the center of the wagon it will pull upon the upper end of the clutch-lever 29 through the medium of the chain 31, disengaging the clutch members. This will throw the reel out of operative connection with the wagon- Wheels and allow the weight of the shock and shock-lifter to open the shock-lifter and deposit the shock in the wagon. The spring 53,*which is secured to the upper end of the standard 3, bears at its free end against the post 54, carried by the horizontal arm 4, to turn said horizontal arm back into outturned position.

When the shock-lifter is carried into raised position, as shown in Fig. 3, it is held there by means of a slide 55, which is carried by a spring 56 into notches 57 in the rods 7. This holds the rods 7 in raised position while the arm 4 is being carried back into outturned position. As it is carried into outturned position a rod 58, connected with the slide, is brought against a pin 59, projecting outwardly from the verticall standard 3, which forces the slide out of locking engagement with the rods 7, allowing said rods to be carried by their own weight and the weight of the shock-lifter into lowered position. This returns all of the parts to the position shown in Fig. 1, ready for a second operation.

I claim- 1. In a shock-litter of the class described, the combination with the wagon, of a horizontal arm supported to swing upon the rear end of said wagon, a shock-lifter slidably supported in the outer end of said arm, a reel, a connection between said reel and said shock-lifter, and tripping means supported in position to be engaged and actuated by an adjacent shock to close and raise said shocklifter through the medium of an interposed clutch, and swing the same inward over the wagon.
